Message to Edit: HTML is ON UBB Code is ON Smilies Legend	Originally posted by Robert Pearlman on 05-08-2010 08:03 AM [QUOTE]Originally posted by Philip: [b]I wonder if there's still good use (weather station?) for a stuck rover...[/b][/QUOTE] To quote Steve Squyres from the release reprinted above: <BLOCKQUOTE>[i]"There's a class of science we can do only with a stationary vehicle that we had put off during the years of driving," said Steve Squyres, a researcher at Cornell University and principal investigator for Spirit and Opportunity. "Degraded mobility does not mean the mission ends abruptly. Instead, it lets us transition to stationary science." One stationary experiment Spirit has begun studies tiny wobbles in the rotation of Mars to gain insight about the planet's core. This requires months of radio-tracking the motion of a point on the surface of Mars to calculate long-term motion with an accuracy of a few inches. "If the final scientific feather in Spirit's cap is determining whether the core of Mars is liquid or solid, that would be wonderful -- it's so different from the other knowledge we've gained from Spirit," said Squyres.[/i]</BLOCKQUOTE>
